PREFACE. 


WHEN  the  first  edition  of  this  work  was  issued,  some 
portions  of  the  country  embraced  within  the  limits  assigned 
to  it  were  imperfectly  investigated  or  wholly  unexplored. 
But  the  discoveries  in  Southern  botany  made  during  the 
last  few  years  by  Feay,  Garber,  Curtiss,  and  others,  of 
tropical  forms  on  the  peninsula  and  keys  of  Florida,  by 
Dr.  Gattinger  of  Northern  forms  which  extend  into  Ten- 
nessee and  the  mountains  of  North  Carolina,  and  by  cor- 
respondents from  other  States,  have  become  so  numerous 
that  a  new  edition  of  the  Southern  Flora  is  required  to 
embrace  them. 

In  this  edition  I  have  concluded  to  incorporate  these 
additions  in  the  form  of  a  Supplement  to  the  first  edition, 
avoiding  any  material  alterations  in  it. 

And  now,  since  the  different  sections  of  all  the  States^ 
which  are  included  in  the  limits  embraced  by  this  work 
have  been  pretty  thoroughly  explored,  and  future  acqui- 
sitions will,  probably,  be  comparatively  few  in  number, 
the  time  seems  to  have  arrived  when  the  promise  pro- 
visionally made  in  the  Preface  to  the  first  edition  may  be 
at  least  partially  fulfilled. 


It  is  my  intention,  therefore,  to  commence  the  prepara- 
tion of  a  final  edition,  which  shall  include  in  their  proper 
place  all  the  acquisitions  made  to  our  Flora  since  the 
publication  of  the  first  edition,  with  the  changes  in  no- 
menclature introduced  during  that  time  ;  and  I  invite 
a  continuance  of  the  co-operation  and  assistance  of  all 
who  are  interested  in  the  successful  prosecution  of  the 
work.

INTRODUCTION. 


I.    SKETCH   OF  THE  ELEMENTS   OF  BOTANY. 

1.    Vegetable   Tissue. 

1.  PLANTS  are  primarily  composed  of  minute  membranous  vesicles  or  cells, 
which  are  endowed  with  the  power  of  reproduction,  and  through  which,  al- 
though closed  and  destitute  of  visible  pores  or  openings,  the  juices  of  the  plant 
are  readily  transmitted. 

2.  Variously  modified,  these  cells  form  the  Elementary  Tissues ;  viz.   Cellular 
Tissue  or  Parenchyma,  Woody  Tissue  or   Woody  Fibre,  and  Vascular  Tissue  or 
Vessels  and  Ducts, 

3.  Cellular  Tissue,  which  exists  in  all  plants,  and  of  which  those  of  the  lower 
orders  are  wholly  composed,  consists  of  cells  aggregated  together,  and  cohering 
by  their  contiguous  surfaces. 

4.  Woody  Tissue  is  composed  of  slender  and  elongated  cells,  with  firm  and 
thickish  walls,  collected  in  threads  or  bundles. 

5.  Vascular  Tissue  is  made  up  of  larger  cells,  either  in  the  form  of  continuous 
tubes,  or  forming  such  by  the  union  of  their  extremities.     In  some  of  these,  the 
walls  are  marked  with  dots,  lines,  or  bands  ;  while  in  others  they  are  lined  with 
spirally  coiled  fibres  which  are  capable  of  being  unrolled.     The  latter  are  called 
Spiral  Vessels,  and  exist  only  in  plants  which  bear  proper  flowers. 

6.  Of  these  tissues  are  formed  the  Organs  of  plants;  viz.  Organs  of  Vegetation, 
consisting  of  the  Root,  Stem,  and  Leaves,  and  Organs  of  Reproduction,  consisting 
of  the  Flower  and  Fruit. 

2.    The   Root. 

7.  The  Root,  or  Descending  Axis,  is  that  part  of  the  plant  which  grows  down- 
ward, commonly  penetrating  the  soil,  from  the  moisture  of  which  it  imbibes 
nourishment.     It  branches  indefinitely  and  without  order,  but  bears  no  other 
appendages.    Its  ultimate  branches  are  called  Rootlets. 

8.  Roots  which  descend  immediately  from  the  embryo  are  termed  Primary 
Roots.    They  are  called  Tap-Roots,  when  they  consist  of  one  thick  and  fleshy 
piece  ;  fascicled,  or  clustered,  when  of  several  fleshy  branches  springing  from  a 
common  centre ;  tuberous  when  the  branches  become  greatly  enlarged  and  filled 
with  starchy  matter;  and  fibrous,  when  all  the  parts  are  slender  and  thread-like. 


X  INTRODUCTION. 

9.  But  roots  under  favorable  circumstances  are  developed  from  other  parts  of 
the  plant.     These  are  called  Secondary  Roots. 

10.  Aerial  Roots  are  those  which  spring  from  the  stem  or  branches  above 
ground.    In  some,  as  in  many  Endogenous  Plants,  they  proceed  from  the  lower 
joints  of  the  stem ;  in  others,  as  the  Mangroves  and  Fig-trees  of  South  Florida, 
they  descend  from  the  branches,  and  at  length,  penetrating  the  soil,  form  new 
stems  in  all  respects  similar  to  that  of  the  parent  tree.    The  tendril-like  roots  of 
some  climbing  stems  are  also  of  this  class. 

11.  Epiphytes  or  Air-Plants,  of  which  the  Tillandsia  and  Epidendmm  are  ex- 
amples, are  those  which  are  borne  on  the  trunks  or  branches  of  trees,  but  draw 
their  nourishment  from  the  air. 

12.  Parasites,  like  Air-Plants,  grow  on  other  plants ;  but  their  roots,  pene- 
trating the  substance  of  the  supporting  plant,  feed  upon  its  juices.    Some,  as 
the  Mistletoe  and  Dodder,  fix  themselves  upon  the  trunk  or  branches ;  others, 
like  the  Beech-drop,  upon  the  root. 

3.    The    Stem. 

13.  The  Stem,  or  Ascending  Axis,  is  that  part  of  the  plant  which  grows  up- 
ward into  the  air  and  light,  bearing  leaves  and  flowers.    It  exists,  under  various 
modifications,  in  all  flowering  plants  ;  but  in  those  which  are  said  to  be  stem/ess 
or  acaulescent,  it  is  very  short,  or  concealed  in  the  ground. 

14.  It  consists  of  a  succession  of  leaf-bearing  points,  or  Nodes,  separated  by 
naked  joints,  or  Internodes.    The  growing  points,  which  are  protected  by  reduced 
leaves  in  the  form  of  scales,  are  called  Buds.     These  are  terminal,  when  they  ter- 
minate the  axis  ;  axillary,  when  they  spring  from  the  axil  of  the  leaves  ;  that  is, 
from  the  point  where  the  upper  surface  of  the  leaf  joins  the  stem ;  and  adventi- 
tious, when  they  are  developed  from  any  other  part. 

15.  Simple  stems  grow  by  the  development  of  the  terminal  bud  alone ;  branch- 
ing stems  expand  indefinitely  from  the  axillary  buds  also.     The  ultimate  divis- 
ions of  the  branches  are  called  branchlets. 

16.  The  jointed  stem  of  Grasses  and  similar  plants  is  a  Culm. 

17.  The  thick  and  simple  stem  of  the  Palmetto  is  a  Caudex. 

18.  A  Rhizoma,  or  Rootstock,  is  a  perennial  stem,  commonly  creeping  on  the, 
ground,  or  beneath  its  surface,  developing  annually  a  bud  at  the  apex,  while, 
the  older  portion  decays. 

19.  A  Tuber  is  a  subterranean  branch,  excessively  thickened  by  the  deposition 
of  starchy  matter,  and  furnished  with  minute  scales,  having  concealed  buds  (eyes) 
in  their  axils. 

20.  A  Corm  is  a  solid  globular  subterranean  stem,  filled  with  starchy  matter, 
with  a  bud  at  the  apex  and  roots  below. 

21.  A  Bulb  is  a  short  subterranean  stem,  made  up  of  the  thickened  bases  of 
leaves,  in  the  form  of  persistent  scales.     It  is  tunicated  or  coated,  when  the  scales 
are  large  and  wrapped  one  within  the  other ;  and  scaly,  when  these  are  small 
and  imbricated.     Small  aerial  bulbs,  such  as  are  borne  in  the  axil  of  the  leaves 
of  the  Tiger-Lily,  and  among  the  flowers  of  the  Onion,  are  called  Bulblets. 

22.  A  Stolon  is  a  branch  which  bends  to  the-  earth,  strikes  root,  and  forms  a 
new  plant. 


ELEMENTS    OF    BOTANY.  xl 

23.  A  Runner  is  a  thread-like  prostrate  branch,  producing  roots  and  a  tuft  of 
leaves  at  its  extremity. 

24.  Spines,  or  Thorns,  are  imperfectly  developed,  leafless  branches,  with  hard 
tips. 

25.  Tendrils  are  the  thread-like  spirally  coiled  branches  of  weak  and  slender 
plants,  by  means  of  which  they  attach  themselves  to  other  and  stronger  objects 
for  support.     Leaf-stalks  and  parts  of  the  inflorescence  are  occasionally  convert- 
ed into  tendrils. 

26.  Plants  which  die  down  to  the  ground  at  the  close  of  the  season,  or  after 
maturing  seed,  are  called  Herbs,  or  Herbaceous  Plants.    Those  with  woody  stems, 
lasting  from  year  to  year,  when  of  humble  size,  are  called  Shrubs,  and  when 
reaching  an  elevation  of  twenty  feet  or  more,  Trees. 

4.    Internal   Structure   of   Stems. 

27.  The  stems  of  Phaenogamous  Plants  are  composed  of  cellular  tissue,  woody 
tissue,  and  vessels ;  and  upon  the  arrangement  of  the  latter  are  founded  the  two 
divisions  of  Exogenous  and  Endogenous  Plants. 

28.  Exogenous  stems  consist  of  a  central  column,  called  the  Pith ;  an  external 
covering,  called  the  Bark ;  and  a  middle  portion,  called  the  Wood. 

29.  Their  Pith  is  a  mass  of  cellular  tissue,  enclosed  in  a  thin  sheath  of  spiral 
vessels,  termed  the  Medullary  Sheath. 

30.  Their  Wood  is  composed  of  one  or  more  layers  of  woody  and  vascular 
tissue,  traversed  by  thin  plates  of  cellular  tissue,  called  the  medullary  rays,  and 
annually  increased,  in  all  perennial  stems,  by  the  addition  of  a  new  layer  to  the 
outside  of  that  of  the  previous  year.     The  new  wood  is  called  the  Alburnum,  or 
Sap-wood,  and  the  older  and  harder  portion,  the  Duramen,  or  Heart-wood. 

31.  The  Bark,  like  the  wood,  is  made  up  of  layers.     The  inner  bark,  or  Liber, 
is  composed  chiefly  of  woody  fibre.     Between  it  and  the  wood,  in  the  growing 
season,  is  secreted  a  thin  mucilage,  called  the  Cambium,  in  which  the  new  layers 
of  wood  and  bark  are  developed.    Surrounding  the  inner  bark  is  the  Green  bark, 
consisting  of  cellular  tissue  filled  with  Chlorophyll,  or  the  green  matter  of  veg- 
etables.    Covering  the  whole  is  a  thin  membrane  of  cellular  tissue,  called  the 
Epidermis,  or  Cuticle. 

32.  Endogenous  stems  exhibit  no  distinction  of  pith,  wood,  and  bark ;  but 
are  composed  of  threads  or  bundles  of  woody  tissue,  irregularly  embedded  in 
cellular  tissue.     They  increase  in  diameter  by  the  formation  of  new  bundles, 
which  are  chiefly  directed  to  the  centre  of  the  stem. 

5.     The    Leaves. 

33.  Leaves  are  expanded  appendages  of  the  stem,  developed  from  axillary 
and  terminal  buds.     They  consist  of  loose  cellular  tissue,  supported  by  a  net- 
work of  woody  and  vascular  tissue,  called  veins  or  ribs,  and  protected  by  the 
epidermis.     In  them  the  fluids  received  from  the  root,  and  what  they  imbibe 
from  the  air,  through  minute  openings  in  the  epidermis,  called  stomata,  are  con- 
verted into  the  proper  food  of  the  plant. 

34.  In  the  bud,  they  are  folded,  plaited,  or  coiled  in  various  ways.     This  is 
termed  their  Vernation. 


XU  INTRODUCTION. 

35.  A  complete  leaf  comprises  the  Blade,  the  Stalk,  and  a  pair  of  Stipules ; 
but  these  three  parts  are  not  always  present  in  one  leaf. 

36.  The  Blade,  Limb,  or  Lamina,  is  the  expanded  part,  and  presents  a  great 
variety  of  forms.     It  is  simple,  when  it  consists  of  a  single  piece,  however  cut  or 
divided ;  and  compound,  when  of  two  or  more  distinct  pieces   (lea/lets),  which 
separate  by  a  joint. 

37.  The  Stalk,  or  Petiole,  connects  the  blade  with  the  stem.     When  it  is 
wanting,  the  leaf  is  said  to  be  sessile.     The  stalk  of  a  leaflet  is  called  a  Petiolule. 

38.  The  Stipules  are  appendages  of  various  forms,  placed  one  on  each  side  at 
the  base  of  the  petiole.     They  are  separate,  or  else  united  with  the  petiole,  or 
with  each  other,  when  they  occasionally  form  a  sheath  (Ochrea)  around  the 
stem  above.    The  stipules  of  a  leaflet  are  called  Stipels. 

39.  The  manner  in  which  the  veins  are  distributed  through  the  leaf  is  called 
Venation. 

40.  There  are  two  modes  of  venation  ;   viz.  parallel-veined,  or  nerved,  when 
several  simple  veins,  or  ribs,  run  parallel  from  the  base  of  the  blade  to  its  apex ; 
and  reticulated,  or  netted-veined,  when  the  veins  divide  into  numerous  primary  and 
secondary  branches  (veinlets),  which  again  unite  to  form  a  kind  of  network. 

41.  The  latter  mode  embraces  both  the  pinnately  veined,  or  feather-veined  leaf, 
where  the  petiole  is  continued  through  the  middle  of  the  blade,  giving  off  at  in- 
tervals lateral  veins ;  and  the  palmately  veined  or  ribbed  leaf,  when  it  divides  at 
the  apex  into  three  or  more  strong  branches. 

42.  The  manner  in  which  leaves  are  divided  corresponds  with  that  of  their 
venation. 

43.  A  simple  pinnately  veined  leaf  becomes  pinnatifid,  when  the  incisions 
(sinuses)  extend  about  half-way  to  the  midrib,  or  continuation  of  the  petiole ; 
and  pinnately  divided,  when  they  extend  down  to  the  midrib.     A  compound  pin- 
nately veined  leaf  is,  of  course,  pinnate,  with  the  separate  leaflets  arranged  on 
each  side  of  the  common  petiole.     When  this  is  terminated  by  a  leaflet,  the  leaf 
is  said  to  be  odd-pinnate,  or  unequally  pinnate,  and  when  it  is  wanting,  abruptly 
pinnate. 

44.  So,  also,  the  palmately  veined  leaf  becomes  palmately  cleft  or  divided, 
when  the  incisions  are  directed  toward  the  base  of  the  blade.     When  the  divis- 
ions consist  of  separate  leaflets,  it  becomes  palmately  compound. 

45.  Floral  leaves,  or  those  from  the  axils  of  which  the  flowers  are  developed, 
are  called  Bracts ;  and  those  which  are  borne  on  the  flower-stalk,  Bractlets. 

6.    The   Flower. 

46.  A  Flower  consists  of  those  parts,  or  organs,  which  are  concerned  in  the 
production  of  seed.     Like  the  leaf,  of  which  its  parts  are  a  modification,  it  is 
developed  from  an  axillary  or  terminal  bud. 

47.  The  manner  in  which  the  flowers  are  arranged  on  the  stem  or  branches  is 
termed  the  Inflorescence. 

48.  There  are  two  modes  of  inflorescence ;  viz.  the  indefinite,  or  centripetal, 
where  the  flowers  all  arise  from  axillary  buds,  the  lowest  or  outermost  expand- 
ing first,  while  the  axis  elongates  indefinitely  from  the  terminal  bud ;  and  the 
definite,  or  centrifugal,  where  the  flowers  arise  from  the  terminal  bud,  first,  of  the 
main  axis,  and  successively  from  that  of  the  branches. 


ELEMENTS    OF    BOTANY.  Xlii 

49.  When  the  flowers  arise  from  the  axil  of  the  ordinary  leaves  of  the  stem, 
they  are  said  to  be  axillary ;  but  oftener,  they  are  disposed  in  a  more  or  less 
obvious  cluster,  each  arising  from  the  axil  of  a  greatly  reduced  leaf,  or  Bract. 

50.  The  stalk  of  a  solitary  flower,  or  of  a  cluster  of  flowers,  is  termed  the 
Peduncle ;  or,  when  it  proceeds  from  the  root,  a  Scape ;  and  that  of  each  indi- 
vidual of  a  cluster  is  called  a  Pedicel.     The  main  axis  of  a  cluster,  or  that 
portion  of  the  common  peduncle  which  bears  the  flowers,  is  called  the  Rachis. 

51.  The  indefinite  inflorescence  includes  the  Spike,  Ament,  Spadix,  Raceme. 
Corymb,  Umbel,  Head,  and  Panicle ;  the  definite,  the  Cyme  and  its  modifications. 

52.  The  Spike  consists  of  a  more  or  less  elongated  rachis,  with  the  flowers 
sessile,  or  nearly  so,  in  the  axils  of  the  bracts. 

53.  The  Ament,  or  Catkin,  is  the  scaly  deciduous  spike  of  the  Pine  and 
Willow. 

54.  The  Spadix  is  a  spike  with  the  flowers  borne  on  a  thick  and  fleshy  rachis. 
It  is  naked,  as  in  the  Golden-club,  or  enclosed  in  a  hood,  called  the  Spathe,  as  in 
the  Indian  Turnip. 

55.  The  Raceme  presents  the  elongated  rachis  of  the. spike,  but  the  flowers 
are  raised  on  pedicels. 

56.  The  Corymb  is  a  short  raceme,  with  the  lower  pedicels  elongated,  so  as  to 
bring  their  flowers  to  the  same  level  as  the  upper  ones. 

57.  The  Umbel  is  a  modification  of  the  raceme,  but  with  the  rachis  so  much 
contracted,  that  the  pedicels  (rays)  apparently  spring  from  a  common  centre. 
When  the  umbel  is  compound,  the  partial  umbels  are  termed  Umbellets. 

58.  A  Head  is  an  umbel  with  sessile  flowers.     The  crowded  bracts  of  this  and 
the  preceding  are  collectively  termed  the  Involucre,  and  those  of  the  umbellets, 
the  Involucel. 

59.  When  the  pedicels  of  a  raceme  or  corymb  are  transformed  into  branches, 
either  simple  or  successively  divided,  the  inflorescence  becomes  a  Panicle. 

60.  When  the  further  growth  of  the  axis  is  arrested  by  a  single  terminal 
flower,  and  from  the  axils  below  branches  are  developed,  each  terminated  by  a 
flower,  and  bearing  branches  in  the  same  manner,  the  inflorescence  is  said  to  be 
cymose  or  centrifugal.     But  it  presents  several  peculiar  forms,  occasioned  either 
by  the  imperfect  development,  or  by  the  entire  suppression  of  some  of  its  parts. 
Some,  as  the  true  Cyme,  are  short  and  expanded ;  others  are  elongated,  like  the 
spike  or  raceme.      In  all,  the  flowers  expand  successively  from  the  summit, 
downward,  or  from  the  centre,  outward. 

61.  The  Flower  consists,  commonly,  of  one  or  more  whorls  of  leaves,  called 
the  Floral  Envelopes,  —  of  which  the  outer  one  is  termed  the  Calyx,  and  the  inner 
one  the  Corolla,  —  an  inner  whorl  of  thread-like  organs,  called  the  Stamens,  and 
one  or  more  central  organs,  called  the  Pistils.    These  are  inserted  on  the  apex 
of  the  axis,  which  here  takes  the  name  of  Torus,  or  Receptacle. 

62.  The  Floral  Envelopes  are  sometimes  wanting ;  but  the  stamens  and  pis- 
tils, being  the  fertilizing  organs,  are,  in  all  perfect  flowers,  always  present. 

63.  The  Calyx  is  composed  of  leaves  (Sepals),  usually  of  a  greenish  color, 
which  are  distinct,  or  united  by  their  margins.   .When  the  floral  envelopes  con- 
sist of  a  single  whorl  only,  it  is  always  a  calyx. 


XlV  INTRODUCTION. 

64.  The  Corolla  is  usually  of  a  thinner  texture  than  the  calyx,  and  variously 
colored.     Its  leaves  (Petals),  when  of  the  same  number  as  the  sepals,  always 
alternate  with  them.    They  are  also  often  united  by  their  contiguous  margins,  to 
form  a  monopetalous  corolla. 

65.  When  the  calyx  and  corolla  are  so  nearly  alike  as  not  to  be  readily  dis- 
tinguished, they  are  collectively  termed  the  Perianth. 

66.  A  flower  is  complete  when  all  its  parts  are  present ;  incomplete,  when  the 
floral  envelopes,  or  a  part  of  them,  are  wanting ;  perfect,  when  the  stamens  and 
pistils  are  borne  in  the  same  flower  ;  imperfect,  or  diclinous,  when  they  are  borne 
in  separate  flowers  ;  regular,  when  the  sepals  or  petals  are  of  uniform  shape  and 
size ;  and  irregular,  when  they  are  unlike  in  shape  or  size. 

67.  Imperfect  flowers  are  further  distinguished  into  moiwecious,  when  those  fur- 
nished with  stamens  (staminate  or  sterile  flowers)  and  those  furnished  with  pistils 
(pistillate  or  fertile  flowers]  are  borne  on  the  same  plant;  dioecious,  when  they  are 
borne  on  separate  plants ;  and  polygamous,  when  both  perfect  and  imperfect  flow- 
ers are  borne  on  the  same  or  different  individuals. 

68.  The  manner  in  which  the  parts  of  the  floral  envelopes  are  arranged  with 
respect  to  each  other  in  the  bud  is  termed  their  Estivation.     They  are  valvate, 
when  their  contiguous  margins  meet,  without  overlapping ;    induplicate,  when 
these  project  inwardly ;  reduplicate,  when  they  project  outwardly ;  imbricated, 
when  the  margins  of  one  overlap  the  adjacent  margins  of  the  two  next  within  ; 
convolute,  or  twisted,  when  one  edge  of  each  piece  covers  the  margin  of  the  one 
next  before  it,  and  the  other  edge  is  covered  by  the  margin  of  the  one  next  after 
it ;  and  plaited,  when  the  parts  are  folded  lengthwise. 

7.    The    Stamens. 

69.  A  Stamen  consists  of  a  sac,  called  the  Anther,  and,  usually,  a  stalk,  called 
the  Filament,  by  which  it  is  supported. 

70.  They  are  hypogynous,  when  they  are  inserted  on  the  receptacle  ;  perigynous, 
when  on  the  calyx ;  epigynous,  when  on  the  ovary ;  epipetalous,  when  on  the  co- 
rolla ;  and  gynandrous,  when  they  are  united  with  the  style.     They  are,  also, 
often  combined  with  each  other,  either  into  one  set  (monadelphous),  or  into  two, 
three,  or  more  sets  (diadelphous,  triadelphous,  &c.). 

71.  The  Anther  is  composed,  commonly,  of  two  united  cells,  which  open  in 
various  ways,  and  discharge  a  yellow,  fertilizing  powder,  called  the  Pollen.     The 
part  which  connects  the  cells  is  the  Connective. 

72.  It  is  erect,  or  innate,  when  fixed  by  its  base  to  the  apex  of  the  filament ; 
adnate,  when  fixed  to  the  filament  by  its  whole  length ;  versatile,  when  fixed  by 
the  middle  to  the  apex  of  the  filaments  on  which  it  turns  as  on  a  pivot :  introrse, 
when  it  faces  inwardly  toward  the  pistils ;  and  extrorse,  when  it  faces  outward  ly 
toward  the  petals.     Occasionally,  they  are  united  into  a  tube  (syngenesious). 

73.  Between  the  stamens  and  the  pistils  is  often  a  fleshy  expansion,  called  the 
Disk. 

8.    The  Pistils. 

74.  The  Pistils  occupy  the  centre  of  the  flower.     They  are  inserted,  singly  or 
in  a  whorl,  on  the  receptacle ;  or,  when  this  is  elongated  or  enlarged,  they  cover 
its  surface. 


ELEMENTS    OF    BOTANY.  XV 

75.  A  Pistil  consists  of  three  parts,  — the  Ovary,  the  Styk,  and  the  Stigma. 

76.  The  Ovary  is  the  lower  and  hollow  portion,  containing  the  Ovules,  or  ru- 
diments of  seeds. 

77.  The  Style  is  an  extension  of  the  ovary,  commonly  of  its  apex,  which  sup- 
ports the  stigma. 

78.  The  Stigma  is  commonly  the  apex  of  the  style,  or,  when  this  is  wanting, 
of  the  ovary,  denuded  of  the  epidermis. 

79.  When  the  pistil  is  composed  of  a  single  piece,  or  carpel,  it  is  simple;  but, 
oftener,  it  is  compound,  consisting  of  two  or  more  carpels,  united  by  their  margins, 
or  by  their  sides,  which  then  form  partitions  or  dissepiments,  that  divide  the  pistil 
into  as  many  cells  as  there  are  carpels. 

80.  The  line  next  the  axis,  or  which  corresponds  to  the  united  margins  of  a 
folded  leaf,  is  called  the  Ventral  Suture;  and  that  which  corresponds  to  the  mid- 
rib, the  Dorsal  Suture. 

81.  The  Ventral  Suture  bears  the  ovules ;  and  the  line  of  their  attachment  is 
called  the  Placenta.     This  is  central  or  axile,  when  it  occupies  the  centre  of  the 
pistil,  and  parietal,  when  it  is  borne  on  its  walls. 

82.  The  Ovule  is  connected  with  the  placenta  by  a  cord,  called  the  Funiculus. 
It  consists  of  a  central  body,  called  the  Nucleus,  enclosed  in  two  sacs,  each  with 
an  opening  at  the  apex,  called  the  Foramen.    The  outer  sac  is  termed  the  Primine, 
and  the  inner  one  the  Secundine.     The  point  where  these  parts  unite  is  called  the 
Chalaza. 

83.  The  Ovule  is  orthotropous  when  the  chalaza  is  next  the  placenta,  and  the 
apex  at  the  opposite  extremity ;  campylotropous,  when  it  curves  on  itself,  so  as  to 
bring  the  apex  near  the  chalaza ;  anatropous,  when  it  is  inverted  on  its  cord,  to 
which  it  adheres ;  the  true  apex  pointing  to  the  placenta,  while  the  chalaza,  or 
true  base,  points  in  an  opposite  direction ;  and  amphitropous,  when  it  is  half  in- 
verted on  its  cord,  its  axis  running  parallel  with  the  placenta.     The  adhering 
portion  of  the  cord  in  the  last  two  cases  is  termed  the  Raphe. 

9.    The  Fruit. 

84.  The  Fruit  is  the  ovary,  with  its  contents,  brought  to  maturity.     But  dur- 
ing this  process  it  sometimes  undergoes  important  changes,  either  by  the  obliter- 
ation or  abortion  of  some  of  its  cells,  partitions,  or  ovules,  or  by  the  formation  of 
false  partitions,  or  by  various  changes  effected  in  its  walls,  or  in  the  parts  which 
surround  them. 

85.  In  some,  the  walls,  or  Pericarp,  remain  closed ;  in  others,  they  open,  or 
are  dehiscent  in  various  ways,  oftener  splitting  regularly  into  separate  pieces, 
called  Valves. 

86.  Many  terms  are  employed  to  designate  the  different  kinds  of  fruit,  but  only 
the  following  are  in  general  use. 

87.  A  Follicle  is  a  simple  fruit,  opening  along  the  ventral  suture  only;  as  the 
fruit  of  the  Milkweed. 

88.  A  Legume  is  a  simple,  fruit  opening  at  both  sutures ;  as  in  the  Pulse  Fam- 
ily.    When  it  is  divided  across  into  closed  joints,  it  is  a  Lament. 

89.  A  Capsule  is  a  dry  compound  fruit,  opening  in  various  ways.     When  it 
opens  at  the  dorsal  sutures,  or  into  the  cells,  the  dehiscence  is  said  to  be  loculicidal; 


XVi  INTRODUCTION. 

and  septicidal,  when  it  opens  at  the  ventral  suture,  or  through  the  partitions. 
When  it  opens  transversely,  the  upper  portion  falling  off  entire,  like  a  lid,  the 
dehiscence  is  circumscissile. 

90.  A  S'dique  is  a  slender  two-valved  capsule,  with  two  parietal  placentae  con- 
nected by  a  persistent  false  partition.     A  short  and  broad  silique  is  a  Silicle. 
These  are  peculiar  to  the  Mustard  Family. 

91 .  A  Pepo  is  the  fleshy  indehiscent  fruit  of  the  Gourd  Family,  with  the  seeds 
often  embedded  in  the  pulpy  placentae. 

92.  A  Pome  is  the  indehiscent  fruit  of  the  Apple  or  Quince  tribe,  where  the 
cells  are  enclosed  in  the  enlarged  and  fleshy  tube  of  the  calyx. 

93.  A  Berry  is  an  indehiscent  fruit,  with  the  seeds  embedded  in  soft  pulp. 

94.  A  Drupe  consists  of  one  or  more  hard  or  bony  cells,  called  the  Puta- 
men,  covered  with  a  fleshy  or  pulpy  coat,  called  the  Sarcocarp ;  as  the  Peach, 
Holly,  &c. 

95.  An  Achenium  is  a  small,  dry,  one-seeded,  indehiscent  fruit,  the  walls  of 
which  do  not  adhere  to  the  enclosed  seed.     When  these  are  closely  united,  it 
becomes  a  Caryopsis;  or  when  the  walls  are  thin  and  bladder-like,  and  open 
irregularly,  a  Utricle. 

96.  A  Nut  is  a  dry,  indehiscent  fruit,  with  hard  or  bony  walls ;  as  the  Acorn 
and  Hickory-nut. 

97.  A  Samara  is  a  dry,  indehiscent  fruit,  with  its  walls  expanded  into  a  wing ; 
as  that  of  the  Maple  and  Elm. 

98.  The  collective  fruit  of  the  Pine  is  called  a  Cone  or  Strobile. 

10.    The  Seed. 

99.  The  Seed  is  the  matured  ovule,  and  contains  the  Embryo,  or  the  rudiment 
of  a  future  plant.     The  outer  coat,  or  Integument,  is  called  the  Testa.    It  varies 
greatly  in  texture,  and  is  occasionally  furnished  with  hairs,  which  either  cover  the 
entire  seed,  or  form  a  tuft  ( Coma)  at  one  or  both  extremities. 

100.  The  terms  employed  in  describing  the  ovule  are  chiefly  applicable  to  the 
seed.     The  foramen  of  the  ovule,  which  is  closed  in  the  seed,  becomes  the  Mi- 
cropyle,  and  is  always  opposite  the  radicle  of  the  embryo.     The  scar  left  on  the 
seed  by  the  separation  of  the  cord  is  the  Hilum.    It  is  sometimes  enveloped  in 
a  false  covering,  originating,  during  its  growth,  from  the  cord  or  from  the  pla- 
centa.   This  is  called  the  Aril. 

101.  The  Testa  includes  either  the  embryo  alone,  or  an  additional  nutritive 
substance,  called  the  Albumen. 

102.  The  Embryo  consists  of  the  Radicle,  the  Plumule,  and  the  Cotyledons. 

103.  The  Eadicle  is  the  first  joint  of  the  stem.    In  germination,  it  elongates 
at  one  end  to  form  the  root,  and  at  the  other,  from  a  minute  bud  (Plumule),  to 
form  the  stem.     It  is  inferior  when  it  points  to  the  base  of  the  pericarp,  and  su- 
perior when  it  points  to  its  summit. 

104.  The  Cotyledons  are  the  seed-leaves.     The  embryo  of  the  Exogenous 
Plants  bears  two  of  these,  placed  opposite  (rarely  three  or  more  in  a  whorl), 
while  that  of  Endogenous  Plants  bears  only  one.     Hence  the  former  are  called 
dicotyledonous,  and  the  latter  monocotyledonous. 

105.  When  the  embryo  is  exposed  to  the  combined  influence  of  air,  heat,  and 
moisture,  it  develops  into  a  growing  plant.     This  is  termed  Germination. 


ELEMENTS    OF    BOTANT.  XV11 

106.  The  preceding  considerations  refer  solely  to  Phaenogamous  Plants,  or 
those  which  bear  flowers,  consisting  of  stamens  and  pistils,  and  produce  seeds, 
which  contain  an  embryo,  or  a  rudiment  of  a  future  plant. 

107.  But  there  are  plants  of  a  lower  grade,  which  do  not  bear  flowers  furnished 
with  ordinary  stamens  and  pistils,  nor  seeds  containing  an  embryo,  but  in  place 
of  seeds  they  produce  minute  powdery  bodies,  called  Spores.     These  are  termed 

11.    Cryptogamons  or  Flowerless  Plants. 

108.  The  stems  of  the  higher  orders  of  Cryptogamous  Plants  —  and  these  only 
are  embraced  in  this  work  —  exhibit  nearly  the  same  anatomical  structure  as 
those  of  Phsenogamous  Plants.     But  they  grow  only  from  the  apex,  without  any 
perceptible  increase  of  diameter,  and  therefore  are  termed  Acrogens  or  Point- 
growers. 

109.  The  different  orders  presenting  no  common  type,  the  habit,  the  mode  of 
inflorescence,  and  the  process  of  fertilization,  so  far  as  it  is  known,  being  different 
in  all  of  them,  the  characteristics  of  each  are  more  conveniently  explained  ir  the 
body  of  the  work,  and  need  not  be  enumerated  here. 

13.     Classification. 

110.  Classification  consists  in  the  arranging  of  plants  possessing  like  structure, 
habits,  &c.,  into  groups,  designating  them  by  proper  names,  and  defining  them 
by  appropriate  characters. 

111.  An  assemblage  of  individuals  which  are  so  essentially  alike  as  to  indicate 
their  descent  from  a  common  parent,  and  which  preserve  their  characteristics 
when  propagated  from  seed,  is  tenned  a  Species.    But  circumstances  connected 
with  the  growth  of  an  individual  may  produce  some  deviation  from  its  ordinary 
state,  and  it  then  becomes  a  Variety. 

112.  When  the  pistil  of  one  species  is  fertilized  by  the  pollen  of  another  allied 
species,  the  result  is  a  Hybrid. 

113.  An  assemblage  of  species  agreeing  with  one  another  in  structure  and  ap- 
pearance constitutes  a  Genus.     In  the  same  manner,  although  with  fewer  points 
of  agreement,  genera  are  collected  into  Orders,  or  Families,  and  these,  in  turn,  into 
Classes. 

114.  But  each  of  these  may  include  members  that  agree  in  some  important 
points,  which  are  not  common  to  the  others.     Of  such  are  formed  the  intermedi- 
ate divisions  of  Subgenera,  Suborders,  and  Subclasses. 

115.  There  are  two  modes  or  systems  of  classification;  the  Artificial  System 
of  Linnaeus,  and  the  Natural  System  of  Jussieu. 

116.  In  the  Artificial  System,  the  Classes  and  Orders  are  founded  on  the  num- 
ber, position,  and  connection  of  the  stamens  and  pistils,  regardless  of  any  other 
relationship.     In  the  Natural  System,  every  part  of  the  plant  is  taken  into  consid- 
eration ;  and  the  Orders  embrace  those  genera  which  agree  with  each  other  in  the 
greatest  number  of  important  particulars.     The  latter  system  is  now  in  almost 
universal  use,  and  is  the  one  adopted  in  this  work.

V.    DIRECTIONS  TO   THE   STUDENT. 


HAVING  acquired  a  general  knowledge  of  the  principles  of  botany,  and  of  the 
meaning  of  the  peculiar  terms  employed  in  the  science,  the  student  proceeds  to 
study  or  analyze  plants,  with  a  view  to  determine  their  names,  and  the  place  the} 
occupy  in  the  system. 

His  chief  difficulty,  at  the  outset,  will  be  to  ascertain  to  which  one  of  the  164 
natural  orders  or  families  contained  in  this  work  the  plant  he  may  have  in  hand 
belongs.  Were  he  to  attempt  to  compare  it  with  the  characters  of  each  order 
successively,  the  task  would  be  tedious  and  discouraging. 

To  obviate  this,  and  to  enable  him  to  refer  any  unknown  plant  directly  to  its 
•proper  place  in  the  Flora,  some  guide,  such  as  is  supplied  by  the  following  An- 
alysis of  the  Natural  Orders,  will  be  necessary.  One  or  two  examples  will  best 
explain  its  use. 

Suppose  we  have  in  hand  a  flowering  branch  of  the  Linden-Tree  or  Bass- 
wood.  Turning  to  the  Analysis  on  page  xxix.,  we  compare  it,  first,  with  the 
SERIES  of  PH^ENOGAMOUS  PLANTS,  with  which  we  find  it  to  agree  in  having 
flowers. 

Then,  dividing  the  branch  across,  we  see  if  it  is  made  up  of  pith,  wood,  and 
bark ;  if  the  leaves  are  netted-veined ;  and  if  the  floral  envelopes  are  in  fours 
or  fives.  Exhibiting  these  peculiarities,  it  doubtless  belongs  to  the  CLASS  OP 
DICOTYLEDONOUS  PLANTS  ;  although,  in  consequence  of  the  minuteness  of  the 
seed,  we  have  not  been  able  to  ascertain  the  number  of  the  cotyledons. 

We  next  see  if  the  ovules  are  contained  in  an  ovary.  This  being  clearly  the 
case,  it  comes  under  the  SUBCLASS  of  ANGIOSPERMOUS  PLANTS.  The  double 
floral  envelopes,  and  the  separate  petals  of  the  corolla,  carry  it  to  the  POLYPET- 
ALOUS  DIVISION. 

Our  attention  is  next  directed  to  the  insertion  of  the  stamens  and  petals, — 
whether  on  the  calyx,  or  hypogynous.  In  our  plant  they  are  hypogynous. 
Then,  if  the  stamens  are  more  than  twice  as  many  as  the  petals.  They  are  so 
in  ours.  Then,  if  the  leaves  are  opposite  or  alternate.  In  ours  they  are  alter- 
nate. Then,  if  the  ovaries  are  more  than  one,  or  solitary  and  1 -celled,  or  soli- 
tary and  2 -many-celled.  In  ours  they  are  solitary  and  5-celled;  bringing  it 
under  the  last  alternative.  Then,  if  the  stamens  are  in  anv  wav  connected 


XXviii  INTRODUCTION. 

with  the  petals,  or  free  from  them.  In  ours  they  are  free.  Lastly,  whether 
they  are  united  into  a  tube,  or  in  clusters,  or  are  all  separate.  In  ours  they  are 
sre  united  in  five  clusters,  and  the  sepals  are  deciduous.  This  brings  our  plant 
to  the  natural  order,  TILIACE^E,  59,  —  the  number  referring  to  the  page  of  the 
Flora  where  the  order  is  described. 

Turning  to  that  page,  and  comparing  our  plant  with  the  character  of  the 
order,  we  notice  their  agreement. 

We  then  proceed  to  find  the  name  of  the  genus.  This  is  readily  done,  in  this 
instance,  by  comparing  the  plant  with  the  two  genera  comprised  in  this  order. 
With  the  first  it  will  be  found  to  agree  in  every  particular, 'and  therefore  we 
need  not  carry  it  further.  We  find,  then,  the  plant  in  question  to  be  a  species 
of  the  genus  TILIA,  so  named  by  Tournefort,  and  commonly  called  Linden  or 


Again,  suppose  the  plant  under  consideration  to  be  the  common  Bear-Grass. 
Having  flowers,  it  is,  of  course,  Phcenogamous.  But,  cutting  across  the  stem,  we 
find,  in  the  place  of  pith,  wood,  and  bark,  a  white  mass  of  cellular  tissue,  stud- 
ded with  minute  points,  which  are  the  ends  of  the  divided  threads  of  woody 
fibre ;  the  veins  of  the  leaf  run  parallel  from  the  base  to  the  apex ;  the  floral 
envelopes  are  in  two  rows  of  three  each  ;  and  the  embryo,  if  examined,  will  be 
found  to  have  but  one  cotyledon.  In  these  respects,  our  plant  differs  widely 
from  the  Class  of  Dicotyledonous  Plants,  and  we  therefore  turn  to  its  alterna- 
tive, the  CLASS  of  MONOCOTYLEDONOUS  PLANTS,  on  page  xxxvii.  of  the  Anal- 
ysis, which,  we  observe,  includes  plants  possessing  these  characters. 

Our  plant,  having  the  floral  envelopes  double,  and  not  glumaceous,  falls 
under  the  second  heading,  marked  with  two  stars  (  *  *  ). 

Proceeding  as  in  the  former  example,  and  carefully  comparing  the  plant  with 
the  analysis  that  follows,  we  see,  first,  if  the  ovary  is  adherent  with,  or  free  from, 
the  perianth.  In  ours  it  is  free.  Then,  if  the  perianth  is  single,  or  double.  In 
ours  it  is  double.  Then,  if  the  calyx  and  corolla  are  alike  or  unlike.  In  ours 
they  are  alike.  Then,  if  the  leaves  of  the  perianth  are  glume-like,  or  otherwise. 
In  ours  they  are  not  glume-like.  Then,  if  the  leaves  are  netted-vcined  or  par- 
allel-veined. In  ours  they  are  parallel-veined.  Then,  if  the  capsule  is  1-celled, 
or  3  -  6-celled.  In  ours  it  is  6-celled.  Lastly,  if  the  anthers  are  introrse  or  ex- 
trorse.  In  ours  they  are  introrse. 

This  brings  us  to  the  natural  order  LILIACE^E,  described  on  page  480  of  the 
Flora.  It  contains  ten  genera,  belonging  to  three  tribes,  the  characters  of  which 
are  briefly  given  in  the  Synopsis.  Our  plant,  by  its  capsular  fruit,  the  separate 
divisions  of  the  perianth,  and  leafy  stem,  comes  under  the  third  tribe,  TCLIPA- 
CE/E.  Of  the  two  sections,  marked  with  a  star  (  *  ),  our  plant  belongs  to  the 
second  ;  having  a  Palm-like  stem.  No.  10,  Yucca,  alone  remains ;  and  to  it 
our  plant  must  belong. 

Turning  to  page  485,  where  this  genus  is  more  fully  described,  we  find  it  to 
embrace  four  species,  divided  into  two  sections  based  upon  the  character  of  the 
stem  and  capsule.  The  short  stem  (excluding  the  scape)  and  dry  capsule  of 
our  plant  belong  to  the  former.  It  contains  but  one  species,  Y.  filamentosa,  L., 
which  we  therefore  find  to  be  the  botanical  name  of  the  plant  in  question.
